performance index
Voltage resistance level (such as PN16, PN25, Class 150/300)
Sealing performance (leakage rate, sealing ring material: nitrile rubber NBR, fluororubber FKM, etc.)
Corrosion resistance and high temperature resistance
Thread accuracy (tolerance grade: precision grade, ordinary grade)

Structure: It mainly consists of threaded parts at both ends and a connecting body in the middle. The threaded part is usually an external thread, and there are also cases of internal threads, used for screwing connection with the internal or external threads of pipes or other fittings; The intermediate connecting body is generally cylindrical or hexagonal, which is convenient for tool operation during installation and disassembly
Principle: By threading, two pipes or fittings are tightly connected together to achieve fluid or gas transmission. During the connection process, the precision of the fit between the threads and the possible use of sealing materials (such as sealant, tape, etc.) ensure the sealing of the connection and prevent medium leakage

Product Overview

1.Material advantage:

Adopting 304 and 316 stainless steel material, 304 stainless steel has good general corrosion resistance and can remain stable in many conventional environments, while 316 stainless steel contains molybdenum, which further improves its corrosion resistance, especially in the performance of chlorine and other corrosive environments, which greatly prolongs the service life of the product, reduces the frequency of replacement, and reduces the maintenance cost.

2. Pressure adaptability advantage:

The pressure rating of 150 LB enables it to operate stably in low and medium pressure piping systems, and it can be widely used in many industrial and civil piping scenarios, such as part of the chemical industry's low-pressure transmission pipelines, building water supply and drainage systems in the specific pressure section of the pipeline connection, etc., to ensure that the system transmits the fluid medium in a safe and efficient manner.

3. Thread compatibility advantage:

Equipped with NPT, BSPT and BSPP threads, NPT thread is the American standard thread, which is widely used in the United States and some regions adopting the American Standard system; BSPT thread is the British tapered pipe thread, which is commonly used in the United Kingdom and the Commonwealth of Nations for piping connections; and BSPP thread is the British parallel pipe thread, which is suitable for specific pipe fitting requirements. This multi-thread design enables the product to seamlessly connect with pipe fittings, valves and other equipments of different standards around the world, which greatly improves the versatility and adaptability of the product, reduces installation problems caused by mismatch of threads, and speeds up the progress of the project.

4. Structural design advantages:

The unique design of hexagonal shape, compared with other shapes of short joints, during the installation process, tools such as wrenches can be more securely stuck in the hexagonal part for tightening operation, providing a larger torqu
 

Stainless Steel 304 and 316 150 LB Hexagonal Splice is available in a wide range of thread types including US NPT, Imperial BSPT and BSPP threads. These products are widely used in industrial piping connections, etc. Stainless steel 304 and 316 materials have good corrosion resistance, strength and durability, and can adapt to different environmental conditions. 150 LB pressure rating meets certain pressure requirements, and a variety of thread forms can be adapted to various types of fittings and equipment, and its hexagonal shape is easy to install and tighten the operation, whether it's in the chemical industry, petroleum, food processing, or construction industries, it can play a key role in the piping system. Whether in the chemical, petroleum, food processing or construction industries, it can play a key role in connecting and transitioning piping systems to ensure the stable operation and sealing performance of piping systems, and is an important choice for high-quality piping connection components.

 

Strong corrosion resistance: Stainless steel material has good corrosion resistance and can resist the erosion of various media such as water, oil, acid and alkali. It is suitable for various harsh working environments and extends the service life of joints and the entire pipeline system.
High strength and pressure resistance: Stainless steel has high strength and hardness, can withstand high pressure, ensuring safe and reliable operation in high-pressure fluid transmission systems, and is not prone to deformation or rupture.
Good sealing performance: Accurate thread processing and appropriate sealing measures enable stainless steel to achieve a good sealing effect on straight through joints, effectively preventing medium leakage and ensuring the normal operation of the system.
Easy installation: Simply tighten the threads at both ends of the joint with the corresponding threads of the pipe or fitting to complete the connection. The operation is simple and does not require complex tools and techniques, reducing installation costs and time.
Strong compatibility: It can be connected to pipes and fittings made of various materials, such as steel pipes, copper pipes, plastic pipes, etc. As long as the thread specifications match, reliable connections can be achieved, which facilitates the construction of pipeline systems made of different materials





Application field category
Building water supply and drainage system: used to connect water pipes, achieve water transportation and distribution, such as the cold and hot water supply pipeline system in buildings such as homes, office buildings, and shopping malls.
Industrial pipeline system: used in the production processes of chemical, petroleum, pharmaceutical, food and beverage industries to connect various process pipelines and transport various fluid media such as raw materials, finished products, wastewater, etc.
HVAC system: plays an important role in the pipeline connection of HVAC equipment such as air conditioning and heating, ensuring the normal operation of the air conditioning system and achieving the regulation of indoor temperature and humidity.
Fire protection system: The connection of fire water pipes requires reliable joints, and stainless steel straight through joints can meet the strength and sealing requirements of the fire protection system for pipeline connections, ensuring timely and effective delivery of fire water in the event of a fire.
Gas transmission system: used for connecting gas pipelines. Due to the corrosion resistance and sealing of stainless steel, it can ensure the safety of gas during transmission and prevent gas leakage.
